What function does the "Export frame" button serve in video editing?

The "Export frame" button in video editing is specifically designed to allow users to save a specific frame from the video timeline as a standalone image file. This function is particularly useful in various scenarios, such as when a user wants to create a thumbnail for their video, capture a moment for promotional materials, or analyze a specific scene without needing to extract the entire video.

When utilizing this feature, the user typically can choose the format of the image file (like JPEG or PNG), along with other details such as resolution, ensuring that the saved frame meets their required specifications. This capability enhances flexibility in content creation and editing, making it an essential tool for any video editor.
